I can be the first sign of death, or help with your next meal. You could say I am persuasive, even if I'm rather dull. There is many a time when I, however, am not dull, and best be avoided especially in hands that are not your own.

What am I?

What can be young or old and only few people can see and people dress like me for halloween

All men have me
I can be long or short
Men give this to women after they are married
And the Pope doesn't use his

A lady goes to a shoe store and buys a pair of high heels. A few days later, she wears them to her job. Since she wore the high heels to her job, she dies. What was here job and how did she die?

3 men are staying at a motel. Unfortunately, they can't afford the rooms. They decide to rent a $30 room together, so each man pays $10. A little later, the manager realized he charged the men too much so he sends a bellhop to them with $5. On the way, the bellhop realized that 5 $1 bills couldn't be divided among 3 men, so he gives them $3, thus each man receives $1 and the bellhop kept the other $2. Because each man paid $10 and received $1, they have all paid $9. 9x3=27, plus the two the bellhop kept is 29. Where's the last dollar?
